Hearing that Ollivander was going to teach himself a new spell, Cowen was looking forward to it, but also noticed Ollivander's hesitant performance in this chat.

From this point of view, this spell may be very precious, and it should belong to the level of the wizard family.

Therefore, Kewen couldn't help but straighten his face and asked seriously: "Is it okay? If you have any difficulties, sir, you don't need to teach me. During the three months of school, I also learned a lot of the rules of the wizarding world, I know Every family has a magic spell that will never be passed on."

Ollivander was slightly taken aback. He didn't expect Kewen to know this, but he still smiled slightly and said kindly: "It's okay, it's okay child, you are worthy of me doing this."

"Then can I know what the spell is?" Kewen continued to say seriously: "Maybe there is also in the library of the college. In that case, if I go to the professors, they will allow me to borrow books, which will not make Mr. You are in trouble."

"No, there is no record of that spell in the academy." Ollivander explained with great relief: "It's easy to say, it's just a memory spell, but as far as I know, in the entire British wizarding world, only your academy's library management The curse of the council, this curse is indeed as you said, it is a secret family tradition, and it is never revealed to the public."

"Then I..." Cowen was surprised, he didn't expect the "memory spell" that Ollivander was going to teach him was such a precious thing.

"I said it doesn't matter." Ollivander smiled and shook his head slightly: "I also said that I hope you can treat me as a family member. Since it is a family member, there is no problem in passing this spell to you."

"Thank you, Mr. Ollivander!" Cowan stood up solemnly and bowed sincerely to Ollivander.

"Haha, get up, kid." Ollivander stretched out his hand with a smile, helped Kewen up, then patted Kewen on the shoulder and said, "With your talent, what you can achieve in the future must be very good. Great. I firmly believe this, and I'm afraid I can't help you more than this 'memory spell'."

"No sir." Kewen shook his head in disapproval and said, "You have given me a lot of help and care, without you, I am afraid I would not have my current life, let alone any future achievements. "

"Okay, let's stop talking about this." Ollivander said, looking at Kewen with more admiration and relief, and sighing: "Your personality is much better now than the month before the school started, when you were compliant, I'm really afraid that you'll be living in self-danger all your life."

"Look at how good your character is now. This far exceeds my expectations. You are more mature and sensible than any child of the same age."

"This is Mr. Ollivander you..."

"Okay, okay, you said it again." Ollivander interrupted Kewen's words with a smile, and then with a stunned look, he said to Kewen, "By the way, if you want to learn the 'memory spell' , you have to learn another spell."

"What more spells do I need to learn?" Kewen asked when he didn't understand.

"The spell to prevent the leakage of the 'Memory Charm'." Ollivander explained: "Although the 'Secret Charm' can also be used to prevent the leakage of the spell, the 'Secret Charm' is not completely safe. 'There is also a risk of leakage if you cast some evil spells."

Cowen frowned slightly, because Ollivander's "secret spell" and "secret" touched his intellectual blind spot.

Seeming to understand Kewen's expression, Ollivander said: "Don't worry about that, you will understand later, let's talk about the spell I want to teach you."

"Okay sir." Kewen obediently stopped thinking about "reading comprehension".

"I want to teach you the insurance spell, called 'Brain Protection Spell', also called 'Occlumency'." Ollivander continued to explain: "This spell can prevent others from reading your thoughts and memories, mastering After you finish this spell, you won't be afraid that others will steal the 'memory spell' from your brain."

"Occlumency..." Kewen murmured in a deep voice.

"What's wrong?" Ollivander asked.

"No, it's nothing." Kewen returned to his senses, shook his head and said, "It's just that I seem to have heard of it somewhere, but I can't remember it."

That's what he said, but Kewen tried his best to recall, and remembered that he had seen this word when he was looking up the data.

Ollivander didn't care after hearing Cowen's answer. He only heard of Occlumency when Cowen was in school.

Therefore, Ollivander said: "We'll talk about Occlumency later, let's learn the Memory Spell first, you come with me."

With a greeting, Ollivander walked to the second floor, and Kewen immediately followed.

Soon, the two came to Ollivander's bedroom. Ollivander asked Cowen to wait, then he walked to the locker, opened the door, and opened a hidden compartment with his wand.

There is only one item in the dark compartment, which is a bottle of potion.

Ollivander carefully took the potion out of the dark compartment, walked towards Cowen, and explained: "The memory spell is just an ordinary spell in the outside world, but like most spells, there are advanced usages. In the same way, memory spells also have more advanced uses."

Coming to Kewen, Ollivander held the potion bottle in his palm and continued to explain: "However, the advanced usage of the 'Memory Spell' needs to be matched with this potion."

"Sir." Kewen was now hungry for magical knowledge, so he couldn't help asking: "What is the effect of ordinary memory spells? What is the effect of advanced ones?"

Ollivander didn't expect that Kewen was still caring about knowledge at this time. After being stunned for a while, he couldn't help but secretly thought that Kewen should belong to Ravenclaw, and he couldn't help laughing.

While smiling, Ollivander also satisfied Kewen's thirst for knowledge, and explained patiently: "Ordinary usage allows you to remember a piece of memory you want to remember, and the memory will become very deep, and it will not follow you. With the passage of time, the memory will be completely forgotten.”

"For example, if you recite a poem, under normal circumstances, after a long time, you will naturally blur the memory of this poem, but if you use the 'memory spell', the memory will never be blurred."

Hearing this, the text couldn't help but couldn't wait to ask: "What about the advanced effects of the 'memory spell'?"

"Advanced effects are amazing." Ollivander said proudly: "Advanced effects can turn your brain into a library, and memory is like various books in the library."

"That's it!" Cowen said suddenly, slightly excited: "It's like you can remember every wand you sell!"

"Haha!" Ollivander smiled and admitted...
